在本发明的制作设备中，首先，内层、内芯层以及外层纸材依次从内而外叠加一起，在叠加之前分别对各层单独施胶，在叠加后一起经过工作平台后端设置的第一压合模组压合，从而形成具有内芯层的平面结构，该平面结构组成 了保护袋。其中，平面结构在与已经制作的另一平面结构重叠后，通过在其中一个平面结构的表面施胶，并对施胶的位置压合，裁切，折边后，形成具有两面平面结构粘合的保护袋。本设备在内芯层制作时，首先将内芯层放卷模组上的模切后的模切纸在未被拉伸的状态下输送至拉伸模组，并在拉伸模组被拉伸后形成网状立体结构的衬垫，之后再将该衬垫作为内芯层纸材夹持与内层和外层之间的位置，一起输送至工作平台，从而形成平面结构，其中立体网状衬垫的内芯层具有更好的保护作用。
再有，该设备根据平面结构的需要可以定制化设置内芯层中衬垫的层数，设置多个任意数量的内芯层放卷模组，适应性较强。
该设备第一施胶模组施胶后，施胶的位置分别经过第一压合模组压合，再在相同的施胶位置由第二施胶模组对平面结构施胶，再由第二压合模组对施胶位置再次压合，保证了相同的施胶位置的多次施胶，相同施胶位置的多次压合，从而形成的保护袋强度较强，不容易破损，质量较高。

参阅图4，该制作设备100包括两个平面制作设备200，该两个平面制作设备200相对设置，平面制作设备200用于制作平面结构10a。
参阅图5及图6，具体的，所述平面制作设备200包括机架21，该机架21包括沿输送方向设置的工作平台211；在本发明的一种优选实施方式中，该机架21为上下层设计，其中上层能够设置外围装置，下层为工作平台211，这样能够使设备紧凑，占地小，节约资源。
其中，平面制作设备200还包括：内层放卷模组221，内芯层放卷模组223，外层放卷模组222，以及第一张力调节装置231，第二张力调节装置232，第三张力调节装置233，拉伸模组24。
具体的，该内层放卷模组221，内芯层放卷模组223，外层放卷模组222均设置于所述机架21的上层结构上，内芯层放卷模组223设置于内层放卷模组221和外层放卷模组222之间，主要用于放卷所述模切纸14a，所述内层放卷模组221、内芯层放卷模组223以及所述外层放卷模组222沿所述输送方向依次设置，其放卷的纸材由内到外依次叠加，即由工作平台211上工作平台211上方叠加在一起。叠加在一起的放卷纸材位于所述工作平台211上向所述输送方向输送。
其中，第一张力调节装置231、第二张力调节装置232以及第三张力调节装置233分别用于调节所述内层纸材、模切纸14a以及外层纸材的张力，放置输送的纸材起皱，折叠等。第一张力调节装置231设置于所述内层放卷模组221与所述工作平台211之间的；第二张力调节装置232设置于所述内芯层放卷模组223与所述工作平台211之间；第三张力调节装置233设置于所述外层放卷 模组222与所述工作平台211之间的。

进一步地，所述第二张力调节装置232对从内芯层12a放卷的模切纸14a张力调节，以使所述模切纸14a在经过所述拉伸模组24之前处于未被拉伸状态；所述第二张力调节装置232包括滑轨、安装于所述滑轨上的滑块、定位于所述滑块上并转动的连接辊以及驱动所述滑块在所述滑轨上滑动的伺服电机，所述模切纸14a穿过所述连接辊。在本实施方式中，所述伺服电机在模切纸14a输送的过程中，自动控制滑块的滑动，当滑块小幅度滑动时，从而带动滑块上的连接辊移动，智能的实现张力的调节；此时夹持在模切纸14a上的张力应该小于模切纸14a被拉伸所需要的最小张力值。
如图8，其中，所述拉伸模组24设置于所述第二张力调节装置232后端，所述拉伸模组24用于将所述模切纸14a拉伸成所述网状立体结构，形成所述衬垫121a并输送至所述工作平台211。
进一步地，所述拉伸模组24包括：过渡辊241以及差速辊242，其中，所述过渡辊241设置于所述第二张力调节装置232后端，用于接收未被拉伸的模切纸14a；所述差速辊242设置于所述过渡辊241与所述工作平台211之间，所述差速辊242转速大于所述过渡辊241，从而将穿过所述过渡辊241的模切纸14a在进入所述差速辊242前被拉伸成所述网状立体结构，从而形成所述衬垫121a。
在本实施方式中，差速辊242与过渡辊241之间的速差似的模切纸14a上的张力大于模切纸14a被拉伸成网状立体结构的最小张力，从而将模切纸14a拉伸，拉伸后的模切纸14a形成衬垫121a，该衬垫121a经过拉伸模组24后进入所述工作平台211，并位于所述内层11a与所述外层13a之间，并一同 输送。

进一步地，第一施胶模组25包括：定位于所述机架21，并沿输送方向相对于所述工作平台211往复移动的支架251；安装于所述支架251上的两个横向喷嘴252以及竖向喷嘴253，两所述横向喷嘴252分别位于所述支架251两侧；所述横向喷嘴252用于对工作平台211上的纸材，在垂直输送方向施胶，所述竖向喷嘴253对工作平台211上的纸材输送方向的中线上施胶。
在本实施方式中，所述内层11a、内芯层12a以及外层13a一起以步进的方式输送，当输送一步停止后，所述支架251从工作平台211边缘的起始点垂直输送方向移动至工作平台211的另一侧边缘，同时两横向喷嘴252在移动的过程中喷出胶水，从而在内层11a、内芯层12a以及外层13a上喷涂上相平行的两行喷胶轨迹，之后输送步进，步进的过程中，竖向喷嘴253打开，在输送方向的中线上喷胶。所述第一施胶模组25使所述纸材形成“H”形施胶轨迹，所述内层11a、所述内芯层12a以及所述外层纸材的施胶轨迹重合。
其中，第一压合模组26设置于所述第三张力调节装置233后端，用于对施胶的粘合位置压合，从而形成平面结构10a。
进一步地，所述第一压合模组26包括多个横向热压单元261和至少一个竖向热压单元262；多个所述横向热压单元261间隔设置于所述工作平台211上，相邻两个所述横向热压单元261的间隔与两所述横向喷嘴252的间距相同；所述横向热压单元261用于对所述横向喷嘴252施胶的位置压合，即对“H”的两竖线位置压合；所述竖向热压单元262用于对所述竖向喷嘴253施胶的中线位置压合，即对“H”的中横线位置压合。
至此，该平面制作设备200制作的平面结构10a完成，两平面结构10a制作形成保护袋时，具体的，两平面制作设备200制作的平面结构10a沿输送 方向叠加一起，并同步输送，并在之后对输送的两平面结构10a中的至少一个边缘表面施胶，压合，裁切形成袋体单元，再对袋体单元的底边涂胶，翻折，折叠后形成保护袋。
参阅图11，其中，所述制作设备100还包括：第二施胶模组12、第二压合模组13以及裁切模组14和涂胶折边模组15。
具体的，第二施胶模组12用于对其中任意一个所述平面结构10a边缘表面施胶，从而使该所述平面结构10a与另一所述平面结构10a边缘粘合；在本实施方式中，该施胶的位置跟第一施胶模组25在平面结构10a上施胶的位置完全相同，且第二施胶模组12与所述第一施胶模组25的结构也完全相同。
第二压合模组13用于压合两所述平面结构10a施胶位置；所述第二压合模组13与所述第一压合模组26结构和在平面结构10a上压合的位置完全相同。
经过第二压合模组13压合后的两平面结构10a形成多个连续连接的“H”形带状结构；两个平面结构10a在“H”形的两竖边与一个横边的位置分别连接在一起，形成一端开口，底部连接在一起的双袋体，连接的底部即为“H”的横线，开口的位置分别是“H”的上端和下端位置。之后再经过裁切模组14对压合后的两平面结构10a一起裁切，形成多个袋体单元。此时袋体单元就是多个分割开来的单个袋体，单个袋体即“H”形双袋体的沿中心横线位置裁切。
如图12，具体的，该裁切模组14包括横向裁切刀141和竖向裁切刀142，所述横向裁切刀141用于对在垂直输送方向的施胶位置裁切；所述竖向裁切刀142用于对输送方向的中线的施胶位置裁切。
